Casement window hinge capable of adjusting window opening angle

Abstract

The invention provides a casement window hinge capable of adjusting a window opening angle. The casement window hinge comprises a sliding rail fixed to a window frame, a fixing strip fixed to a window sash, a hinge wrap angle fixed to one end of the sliding rail, and a sliding block fixed in the sliding rail and capable of sliding; the fixing strip is fixed to the sliding block through a first connecting plate; the fixing strip does angular motion relative to the sliding rail when the sliding block slides; the casement window hinge further comprises a locking block used for limiting the sliding stroke of the sliding block in the sliding rail; the sliding rail is provided with a sliding groove; when the locking block is in a first state, the locking block can slide in the sliding groove; and when the locking block is in a second state, the locking block is fixed in the sliding groove. According to the casement window hinge capable of adjusting the window opening angle, the locking block is selectively dismounted and mounted in the sliding groove, and therefore the window opening angle can be adjusted according to the actual situation, the casement window hinge does not need to be dismounted, mounted and replaced again, and the beneficial effects of saving time and labor and being low in cost are achieved.

Description

technical field [0001] The invention relates to the field of window fixing hinge structures, in particular to a casement window hinge capable of adjusting the window opening angle. Background technique [0002] The casement window has the advantages of large opening area, good ventilation, good sealing, sound insulation, heat preservation, and impermeability, and is deeply loved by the public. The inward opening type is convenient for cleaning the window; the outward opening type does not take up space when opening. . [0003] see figure 1 , the common casement window fixed hinge includes a slide rail fixed on the window frame, a fixing bar fixed on the sash, a sliding block fixed in the slide rail and slidable, one end is rotatably fixed on the sliding block, and the other end The first connecting plate which is fixed on one end of the fixed plate by rotation, one end is fixed by rotation in the slide rail, the other end is fixed by rotation on the second connection plate...

Problems solved by technology

And with the development of society, the industry's standard for the opening range of the window sash has also been updated. In order to adapt to the new standard for the opening range of the window sash, if the fixed hinge of the original casement window that has been installed is replaced with a new one The fixed hinge of the window, on the one hand, the project of disassembly and assembly is relatively large, which is time-consuming and laborious; on the other hand, the re-assembly and disassembly will bring greater cost
